Patent number: 9308764Abstract: A sheet for ink-jet printing including a base sheet 1 and a printing layer 3 formed on a surface of the base sheet 1 and containing a plaster (shikkui) and an organic binder, wherein the printing layer 3, further, contains at least one kind of additive selected from the group consisting of glycerin, water-soluble polymer and non-ionic surfactant. The sheet for ink-jet printing promotes the carbonatation of the plaster (shikkui) after the printing so that the printed image quickly exhibits fastness and weather-proof property due to the carbonatation of the plaster (shikkui).Type: GrantFiled: May 31, 2013Date of Patent: April 12, 2016Assignee: TOKUYAMA CORPORATIONInventors: Koki Hirayama, Tadashi Fujimoto

Patent number: 6972840Abstract: Optical emission spectra from a test wafer during a plasma process are measured using a spectrometer. The plasma charging voltage retained by (detected by) the test wafer is measured after the process step is completed. The emission spectra are correlated with the plasma charging voltage to identify the species contributing to the plasma charging voltage. The optical emission spectra are monitored in real time to optimize the plasma process to prevent plasma charging damage. The optical emission spectra are also monitored to control the plasma process drift.Type: GrantFiled: October 6, 2003Date of Patent: December 6, 2005Assignee: LSI Logic CorporationInventors: Shiqun Gu, Peter Gerard McGrath, Ryan Tadashi Fujimoto

Patent number: 6806038Abstract: A method for forming a conductive trace on a substrate. The conductive trace is patterned with a photoresist mask and etched, thereby forming a polymer layer on a top surface and sidewalls of the photoresist mask and on sidewalls of the conductive trace. The polymer layer contains entrained chlorine gas. The substrate is heated on a chuck in a reaction chamber. A remote plasma is generated from ammonia gas and oxygen gas. The substrate is contacted with the ammonia and oxygen plasma, thereby withdrawing a substantial portion of the entrained chlorine gas from the polymer layer. A radio frequency potential is applied to the chuck on which the substrate resides, thereby creating a reactive ion etchant from the ammonia and oxygen plasma in the reaction chamber and removing the polymer layer from the top surface of the photoresist mask. The photoresist mask is thus exposed, and then removed in an ashing process.Type: GrantFiled: July 8, 2002Date of Patent: October 19, 2004Assignee: LSI Logic CorporationInventors: Shiqun Gu, Hong Lin, Ryan Tadashi Fujimoto

Patent number: 6504533Abstract: An image display apparatus capable of displaying an image signal of an unknown type. Characteristics of an input image signal are examined and, based on the examined characteristics, an attempt is made to identify the input signal as one of a known type. When the input signal can be identified as one of a known type, the signal is converted into a form suitable for display based on retrieved parameters corresponding to the signal's type. When the input signal can not be identified as one of a known type, the number of vertical lines in the signal is multiplied by a predetermined constant and the resulting product is used to convert the signal into a form suitable for display.Type: GrantFiled: April 17, 2000Date of Patent: January 7, 2003Assignee: Sony CorporationInventors: Hiroshi Murayama, Tadashi Fujimoto
